DNS64 is not the only solution for a ISP to go IPv6 only.
64 was motivated by the need for a 6-only *enterprise*
And DNS64 requires NAT in the core and a fork lift upgrade of the
CPE to support IPv6.
no. let's try reading what i said again. i requires nat at the edge of
the V6-ONLY ENTERPRISE. considering the enterprise is v6-only and
trying to talk to a v4 world, address translation is inevitable.
Yet we have ISPs trying to use / contemplating using DNS64.
DS-Lite in the enterprise would require moving DL-Lite to the node
and not all nodes. Just those that need to communicate with the
outside world. For most of those boxes it's just a reuse of existing
stack functionality.
